Steppenwolf (originally Der Steppenwolf) is the tenth novel by German-Swiss author Hermann Hesse. Originally published in Germany in 1927, it was first translated into English in 1929. The novel was named after the German name for the steppe wolf. The book is presented as a manuscript written by its protagonist, a middle-aged man named Harry Haller, who leaves it to a chance acquaintance, the nephew of his landlady. The acquaintance adds a short preface of his own and then has the manuscript published. The title of this "real" book-within-the-book is Harry Haller's Records (For Madmen Only).
